There are actually two variants of Go-Explore in the original paper: one in which we directly reset the agent to an interesting goal (restore-based Go-Explore), and one in which the agent has to act to get back to the proposed goal (policy-based Go-Explore). In this work, we focus on the latter approach, which is technically part of the literature on intrinsic motivation, in particular intrinsically motivated goal exploration processes (IMGEP) [1]}. Note that post-exploration does not require any changes to the IMGEP framework itself, and can therefore be easily integrated into other existing work in this direction.
